Coronation Street lines up horror scenes on Friday night, as Carla Connor will be left for dead by killer Stephen Reid.
He takes action against her amid his plan to destroy her, and take Underworld from her.
The factory boss has been struggling recently, and believes she may be experiencing severe psychosis again - a few years on from her breakdown.
What she doesn't know is that Stephen has been drugging her with LSD for weeks, and this has been the cause of her feeling paranoid and acting out of character.
Things take a deadly turn on Friday night, with spoilers teasing a possible exit for Carla actress Alison King - but does Carla die?
What we know is that Stephen decides to take aim at her yet again after giving her a double dose of LSD during Wednesday's episode.
Pretending to be concerned for Carla, he's playing on her mental health battle and the concern of her loved ones in a bid to get her out of the way.
After being left furious with her this week when she showed him up at work, he drugged her and watched on as she lashed out at her colleagues.
On Friday, fans will see Carla once again speaking to the doctor and she is advised to go back onto prescribed diazepam.
No one suspects Stephen, and he makes his next move as he decides to set her up once more - but this time he could go too far.
As Carla takes her medication and goes to sleep at her flat, Stephen sneaks in to make sure she is asleep.
Confident she's not going to wake up, he sets out to make her look unstable but his action could kill her in the process.
Stephen turns on the grill as Carla sleeps to make it look like she's forgotten about it, leaving her in danger.
He soon sneaks out happy with his efforts - but will someone find Carla before it's too late?
Coronation Street airs Mondays, Wednesdays and Fridays at 8pm on ITV1 and ITV X.
